    Abstract:
    Antibodies to human neutrophil alloantigens (HNA) can cause immune-mediated neutropenias and transfusion complications. The diagnosis of antibodies to the HNA-5a (Ond) isoform of the alphaLbeta2 integrin is hampered by the lack of reliable methods for HNA-5a antigen typing. We have devised a polymerase chain reaction sequence-specific primer method (PCR-SSP) and used it to determine the HNA-5a gene frequencies in 320 individuals from different ethnicities. 15.3% were found to be HNA-5a negative, with no significant deviation between the populations. Results of HNA-5a genotyping were in accordance with phenotyping. Availability of HNA-5a PCR-SSP will facilitate the diagnosis of Ond antibody-mediated clinical conditions.
